Abstract (en)
[origin: EP1247785A2] A resistor solidified from the melt, especially for a refractory molding, comprises refractory mineral metal oxide(s) as main component (I) and an elasticizer (II), comprising a spinel, in an amount exceeding its solubility in (I), so that (II) forms deposited fields in (I). The resistor is produced by fusing (I) and the oxides forming (II) together. A resistor solidified from the melt, especially for a refractory molding, comprises refractory mineral metal oxide(s) as main component (I) and an elasticizer (II), comprising a spinel, in an amount exceeding its solubility in (I), so that (II) forms deposited fields in (I). The resistor is produced by fusing (I) and the oxides forming (II) together. The elasticizer (II) is of general formula: A<2+>B<3->2O4. An Independent claim is also included for the production of the resistor by mixing and melting (I) and the required amount of spinel-forming oxides so that spinel deposits form in the (I) on cooling the melt.
